Santa Rosa Island Noxious Weed Survey and Eradication TOP Channel Islands Restoration is working with the Santa Barbara County Agricultural Commissioner's office an Channel Islands National Park to eradicate two highly destructive weeds on Santa Rosa Island: Cirsium ochrocentrum (yellowspine thistle) and Solanum elaeagnifolium (silverleaf nightshade). Cirsium ochrocentrum is designated by the California Department of Food and Agriculture as an “A” rated noxious weed. “A” rated noxious weeds are plants of know economic importance subject to enforcement action and are the highest priority for eradication by the California Department of Food and Agriculture. Populations of this weed are of very limited distribution in California. Large infestations could ruin a landscape for recreational activity or wildlife habitat. Cirsium ochrocentrum is rare in Santa Barbara County and is only know to occur on Santa Rosa Island. Solanum elaeagnifolium is designated by the California Department of Food and Agriculture as a “B” rated noxious weed. “B” rated noxious weeds are plants of known economic importance. They are regulated and enforcement action is taken at the discretion of the local agricultural commissioner, or when found in a nursery. Populations of this weed are limited in distribution in California. The berries and foliage are poisonous to livestock. Large infestations could potentially compete with native plants for nutrients and moisture. Solanum elaeagnifolium is rare in Santa Barbara County. Thanks to David Chang for information on both weeds.

Volunteers receive briefing from Park Service personnel prior to surveying for Cirsium and Solanum.
